In computer programming, a sigil (/ˈsɪdʒəl/) is a symbol affixed to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo
, where $
is the sigil.
Sigil, from the Latin sigillum, meaning a "little sign", means a sign or image supposedly having magical power.[1] Sigils can be used to separate and demarcate namespaces that possess different properties or behaviors.
